Refractories (Refractory material) selection and matching recommendation (a) burning on both sides of the transition zone within the band and have a stable kiln brick skin site should be used, including magnesium chrome brick, low chromium and chromium-containing zirconium and not zirconium-containing various types of special brick and dolomite bricks. On the production capacity of small, low-temperature kiln, open quite yet more frequent high alumina brick kiln can also be used, mainly phosphate bonded alumina bricks. Refractory ramming tamping method using semi-wet state construction refractory mix called refractory ramming. And the refractory may be of different plastics, such refractory mix is ??a low or no plastic tamping of plastic material, is forced, tamping to form a dense body, and then by heating and baking or roasting occurs hardening to obtain a certain structural strength. Now tamping method of construction materials, in addition to plastic (wet ramming) and ramming (semi-wet ramming) carbon brick physical and chemical indicators, is a completely non-plastic ramming. Past refractory ramming materials and more varieties of MgO-C size, use a wider scope, but because ramming construction labor-intensive, long-time carbon brick construction work price, it is difficult to obtain uniform lining of the body as a whole, has been gradually unshaped refractories (Refractory material) replaced by other construction methods. Now use this semi-wet state ramming few places. Currently ramming the main varieties are: aluminum - Magnesia ramming mixes, high-alumina (or corundum) - silicon carbide - carbonaceous ramming, basic refractory ramming and zirconium mullite ramming materials.
